 A trivial to use IPC solution based on POSIX named pipes and newlines.
 
 ## Why?
@@ -42,6 +42,7 @@ This may sound discouraging, but this is the exact reason why I've written this
 so you won't have to.
 And solving all these issues are worth it in the end: writing clients is as trivial as it gets.
 
+## What?
 This package provides robust, asynchronous servers capable of IO over a text-based,
 newline delimited protocol using named pipes.
 This makes it extremely easy to integrate any external process as a plugin

+A few lines of code are worth a 100 lines of API documentation.
+You can find a simple usage example of this package in `echo_server.py`.

 - `pipe_io_server/clients` contains examples on how to use pipes in different languages
 - `pipe_io_server/test_pipe_io_server.py` contains a relatively comprehensive suite of unit tests
